"I can never see God except in that [itself] in which God sees Himself [inwardly]."
"Niemermê enmac ich got gesehen wan in dem selben, dâ got sich selben inne sihet."
Meister Eckhart, Sermon 69 (or 42) on Jn 16:16 in German, as trans. Maurice O’C. Walshe (Complete mystical works of Meister Eckhart (New York: A Herder & Herder Book, The Crossroad Publishing Company, 2009), 236, inexpert interpolations mine. German from p. 175 l. 5 of Meister Eckharts Predigten, ed. Quint, Bd. 3, Die deutschen Werke 3 (1976) =l. 12 of Predigt 69. For an earlier edition, see p. 144 of the 1857 edition by Pfeiffer.
Eckhart refers next to the "inaccessible light" in which, according to St. Paul, "God dwells," but would it be twisting him (with whose thought I am extremely unfamiliar) to see the eternal Word in this (and therefore ultimately the Incarnation), too? In context, probably.
